Interesting. Apparently there is a similar issue with the Mac version. I personally use Windows, so my knowledge of both Mac and Linux is very limited, but at least for the Mac version I have a solution. Maybe that can help guide you in the right direction?
Try this terminal command to set the application to the executable:
sudo chmod -R +x /PathToYourInstallOf/CrimsonHigh.app/Contents/*
Then enter your admin password.
As far as I understand it, the pathing got funked up somewhere along the way and this command (or a similar linux alternative) fixes it.
